Rathalos are Flying Wyverns introduced in Monster Hunter.

MH4-Rathalos Render 001


Rathalos are large, bipedal wyverns with a spiny, armored hide covering their body. Their outer shell features much brighter and more vibrant colors than that of their female counterpart, the Rathian. It is primarily bright red, with black markings throughout. Like the Rathian, Rathalos possess a flame sac which is used to produce deadly flaming projectiles from the mouth. The talons upon a their feet are highly poisonous and are known to to inflict toxic mortal wounds on larger prey. In addition, their long, thick tail features a heavy spiked club at the end. Rathalos' wing membranes feature ornate patterns which are likely used to attract potential mates.


Rathalos are expert flyers, and as such are prone to hunting from the skies. By launching a surprise aerial attack, they can inflict poisonous wounds with their talons or burn prey with flaming projectiles. On the ground, Rathalos remain formidable opponents. Using their powerful legs, they can chase down prey from a distance or inflict blunt-force damage with their clubbed tail. At a close enough range, they are known to use their sharp teeth to bite at foes as well.


Rathalos are highly territorial monsters, and as such, are aggressive towards intruders. They will chase away or attempt to kill any monster which may pose a threat to their land. While hunting, Rathalos will stalk prey from the air before swooping in for the kill. Once they have successfully brought down their prey, they will carry it away to eat in private, safe from scavengers or other large monsters which might attempt to steal the kill.


Rathalos have been spotted in many kinds of environments, from the temperate Forest and Hills to the extreme heat of the Volcano. As a master of flight, they will travel far and wide, searching for prey from the skies.

  • Rathalos may use his dive bomb attack as the very first attack during a hunt (though this happens quite rarely).
  • So far Rathalos have appeared in every single Monster Hunter game in the series, even including the spin-off MH Diary: Poka Poka Felyne Village.
  • According to one of the Uniqlo Monster Hunter 10th Anniversary T-Shirts, the size of the foot of a Rathalos is 221 centimeters. This may also apply to Azure Rathalos, as the shirt is focused on the main monsters of every generation.
  • Rathalos' roar requires Earplugs to block.

  • Rathalos is the flagship monster of the original Monster Hunter game, and is often considered by fans as the flagship monster of the entire series.

  • Just as with Rathian, Rathalos can pin down a hunter and restore lost Stamina, this can be stopped by running and tripping. Rathalos is weakest to Dragon, followed by Thunder. Also, like Rathian, breaking the wing(s) does not stop its aerial attacks or travel. It can recover Stamina by eating a medium-sized Herbivore, mainly Aptonoth, Slagtoth, and Gargwa.

  • Its back can be broken.
  • Rathalos gains some new moves.
    • During Rathalos' dive bomb attack, he will now breathe fireballs during that attack, so the hunter can not stand still and heal or sharpen like in generations before.
  • In G rank it can do Azure Rathalos' claw attacks.
  • It can be infected by the Frenzy Virus.

  • Rathalos can be a pet.
  • HC Rathalos' roar requires HG Earplugs to block.
